How to pass some parameters to function called in addEventListener?
javascript
Solution
You don't. Use anonymous functions:
document.getElementById('date_right').addEventListener('click', function () {
switch_date(1);
}, false);
document.getElementById('date_left').addEventListener('click', function () {
switch_date(-1);
}, false);
Or use named functions which do not take arguments:
function onRightDateClick() {
switch_date(1);
}
function onLeftDateClick() {
switch_date(-1);
}
document.getElementById('date_right').addEventListener('click', onRightDateClick, false);
document.getElementById('date_left').addEventListener('click', onLeftDateClick, false);

Possible Duplicate: How to pass arguments to addEventListener listener function? How can I pass some argument (in this case an integer) to a function through `addEventListener` on a `click` event? I have two buttons; if I press the right one I want to do some stuff, if I press the left one then I'd like it to do something else. Here's the code: ``` document.getElementById('date_right').addEventListener( 'click', switch_date(1), false ); document.getElementById('date_left').addEventListener( 'click', switch_date(-1), false ); function switch_date( k ) { if(k==1) { //do stuff } else { //another stuff } } ```
